Could anyone recommend a specialist good with the LT77.
Gearbox is a little noisy and the shift isn’t positive so I’d like to get it looked at/overhauled.
Thanks

Not used them for a gearbox I would probably be looking at Ashcroft Transmissions.

Sadly the above don’t touch 2wd transmissions so it went to these in the end.
Quick turnaround and reasonably priced.

Can I ask what they did and how much (approx) it set you back? The reverse in my Westfield Seight with LT77 is near impossible to find so am seriously considering to send it off too...

"Bernie the 'Box" aka Gearboxman fixed my LT77 when I broke a selector fork a few years ago. I was very happy with the work.

Mine came to £450, had new bearings, some new synchros, new pump and gaskets.
Funny enough mine is in a Seight!
There are some good notes here regarding adjustment if you want to try that, poly bushes to the shift housing are a good upgrade too.

Cheers for that! What a coincidence. What's the spec on yours? Mine's a 2002 3.9L EFI with the LT77. Only got it 3 months ago and currently putting things right before the weather starts to improve again.

I've got the bushes ordered as per the gomog article the ones that are in at the moment are perished which causes the whole remote linkage to move when you shift, but I'm not sure I can actually remove the remote linkage from the gearbox whilst it is in the tunnel. Do you happen to know?

2004 built 3.5 on a 4 barrel carb.
Just fitted a recon short engine and refurbished the box too.
Plan to enjoy for a summer or two and then sell.
You can get the housing off without gearbox removal, fiddly but doable.
On mine I went in from the top as the aluminium panels inside are easy to remove.

This is the current state of mine as I'm replacing the awful blue interior with black, so I've got reasonable access to the top too. Good to hear it can be done; as coincidence it would have, my SuperPro poly bushes arrived today as well...

Lol, I've got a more hideous cream interior but don't want to spend any more on it.
The car belonged to a mate who thought it was a good idea at the time!

Hi
I also live in S Wales. Gloucester Road Gearboxes in Bristol have a good reputation and overhauled a camper van gearbox for me recently
